. Thisinvention relates to axle boxes'for vehicles of the type in whichoilfor the purpose of lubricatingthe journal piece of the axle isretained in a container under the Such boxes are usually provided with adevice called a dust ppcket for protecting the oil in the container fromdust andlike foreign matter.

In axle boxes of the above' mentioned character, if the vehicle issubjected to considerable vibration or to sudden changes in directionthe oil spills over the edges of the container or oil bath and floodsthe dust pocket. This fault isparticularly prevalent in axle bearings onrailway vehicles wherein the oil is supplied mechanically by bucket orcentrifugal action as such bearings have large oil baths and nolubricating device in the box under the axle limbs which might damp themovement of theoil.

- It is the object of the present invention to prevent the oil frompassing into the dust pocket. v j

In accordance with the present invention a transverse wall-having aconchoidal cross a section is mounted between the container or oil bathand the dust pocket and extends over a projection of curved crosssection on the bearing box.'

The invention will be described in conjunction with the accompanyingdrawings of which Fig. 1 shows a longitudinal section of the lower halfof-a. vehicle axle box,

5 whilst Fig. 2 shows'two cross sections on the 1 lines A B and C D. A Bbeing a view towards the emergency path and C D a View towards the oilbath. 1

Referring to the drawings a is the oil bath, 1) the journal "piece ofthe axle, e the dust pocket, d the transverse wall of curved crosssection between the -oil bath andthe dust pocket, f the collecting shellon the lower part of the bearing box, and gthe projection which extendsunder the portion d.

of curved crosssection on the bearing box f to one another,

The portion d as above described has a cross section of curvedor'arcuate shape and this wall 03 extends in substantially a quadrantunder the oil collector f, asshown more particularly in Figure 2. t

.1 Extending from the dust chamber back to the oil reservoir is a smallduct h. This duct It is of such cross section that the oil dripping fromthe axle b will be led back i into the-oil reservoir through the duct h,but when the box" is subjected to shocks, sufiicient oil'will not beinjected into the dust receptacle to cause any damage but will flow Theprojectiong is also curved in conformity with the oil collector fasshown pa ticularly inFigure-2 and as above stated, his projection hasa curved or arcuate cross section.

Various modifications will naturally sug gest themselves to thoseskilled in the art without departing from the spirit of my invention.

What I claim is 1. In a bearing b OXffOI' vehicle axles, a. bearing, adust pocket, an oil collecting shell disposed belowsaid bearing, aprojection thereon curved in cross section, a transverse wall separatingthe shell and the pocket, said wall having a curved ,cross section andextending partly over the projection in overlapping relation.
